I am using Bugzilla 4.4.1 from last 2 years with Mysql 5.1.52 and perl 5.10 .1. I have too many data on it.But now I want to use Bugzilla 5.0 with Mysql 5.6.26 and perl 5.10.1.

I have install Bugzilla 5.0 and restore the database from my old Bugzilla 4.4.1. It is restore successfully and access and i can able use but when I try to write new bug or edit exiting bugs no operation can perform while pressing submit button.

Give me a solution for how can upgrade or migrate my Bugzilla 4.4.1 to Bugzilla 5.0.
